摘要

Takotsubo综合征(TS)的特征是一种独特的短暂性左心室壁周运动异常(LVWMA)。TS的左室左壁动脉可定位于左心室的心尖区、心尖中区、心室中区、基底中区或基底区。局灶性和广泛性(全球)LVWMA也有报道。在TS急性期,基底节段瓣膜样运动和/或根尖节段弹弓样运动的高运动结合a-僵硬、低运动节段导致收缩期明显的左心室肿胀。TS的左室wma最可能跟随局部心脏交感神经分布,由局部心脏交感神经中断和去甲肾上腺素溢出引起。

Acute cardiac sympathetic disruption and left ventricular wall motion abnormality in takotsubo syndrome.

Takotsubo syndrome (TS) is characterized by a unique pattern of transient circumferential left ventricular wall motion abnormality (LVWMA). The LVWMA in TS may be localized to the apical, mid-apical, mid-ventricular, mid-basal or basal regions of the left ventricle. Focal and generialized (global) LVWMA have also been reported. In the acute phase of TS, the hyperkinetic valve-like motion of the basal segments and/or the hyperkinetic slingshot-like motion of the apical segments combined with the firm stunned a-, hypokinetic segments result in a conspicuous left ventricular ballooning during systole. The LVWMA in TS follows most probably the local cardiac sympathetic nerve distribution and caused by local cardiac sympathetic disruption and noradrenaline spillover.
